Answer:

2x ^5 sqrt( 6x)

Step-by-step explanation:

sqrt( 3 x^4) * sqrt( 8 x^7)

Multiply them together

sqrt( 3x^4 * 8x^7)

sqrt( 24 x^ (4+7))

sqrt( 24 x^11)

We can simplify

sqrt(24) sqrt(x^11)

sqrt( 4*6) sqrt( x^10) sqrt(x)

sqrt(4) sqrt(6) x^5sqrt(x)

2 sqrt(6) x^5sqrt( x)

Combining the square roots

2x ^5 sqrt( 6x)

Find f(-3), f(-1), and f(1)

suter [353]

Answer:

I will just show you how to substitute.

Step-by-step explanation:

all you have to do is just plug f(x) into the number you want. So if you see any x's, all you gotta do is plug that number after f for x.

So an example of an equation for one of your number is:

$f\left(x\right)=x^2+x$

you then want to plug the number after f for the x's. (I'm doing f(-3).

$f\left(-3\right)=\left(-3\right)^2-3$

You then should get the equation above.

after that you solve.

$f\left(-3\right)=9-3$

$f\left(-3\right)=6$

just follow these steps and you should be fine :))

Three vertices of a rectangle have coordinates (3,4), (5,−4), and (−7,−7). Determine the fourth vertex of the rectangle and then

Ket [755]

The fourth vertex would be at point (-9,1).
The slope from (5,-4) to (3,4) is -8/2 or -4.
So I did that with (-7,-7) to the fourth vertex to get the answer.
